Simultaneously with the emergence of the continental drift hypothesis, Li Siguang actively approached and dealt with the problem of continental crust horizontal movement and, in combination with the reality of China's mainland, developed the theory of intracontinental collision deformation, i.e., the geomechanic theory and method that included the global continental tectonic system.

Firstly, we collected and sorted out the GPS data, established the uniform velocity field for the Chinese mainland and the surrounding regions, and the horizontal deformation field relative to the Eurasia plate; Secondly, we established a motion model for the entire rotation and homogeneous strain of the first and second level blocks in Chinese mainland, analyzed the motion pattern and strain behavior of active blocks in Chinese mainland, as well as the motion pattern of principal fault zones in Chinese mainland; Thirdly, considering the heterogeneity of strain distribution inside a block and supposing that the strain tensor inside the block is the linear function of location, we derived and established an equation for the entire rotation and linear strain of block and a motion model for the entire rotation and linear strain of principal blocks in Chinese mainland; We also calculated the principal strain field and the maximum shear strain field in Chinese mainland and the surrounding regions, analyzed the basic characteristics of strain field in Chinese mainland, as well as the relationship between the spatial distribution of strain field and large tectonic zones; Finally, we established the 2-D geotectonic model and digital model for Chinese mainland and the surrounding regions, calculated the stress field in Chinese mainland and the surrounding regions, and analyzed the basic features of stress field in Chinese mainland and the principal driving force for the motion and deformation in Chinese mainland.

Results show that the Spiti shale in Zanskar terminated 15Ma later than that in southern Tibet, while the lowermost Cretaceous quartz sandstone in Zanskar appeared 18Ma later than that in southern Tibet. The age of volcanic sandstone in southern Tibet is very poorly time constraint and their deposition occurred somewhere within Berriasian~early Albian. In Thakkhola, the Chukh Group volcanic sandstone are of late Hauterivian-early Albian age (duration about 20Ma), while in Zanskar, the volcanic sandstones facies only appeared in Albian (duration of less than 10Ma). Therefore, it can be concluded that the onsets of both quartz sandstone and volcanic sandstone occurred earlier in eastern Tethys Himalayas than in western Tethys Himalayas .
侏罗纪末~白垩纪初印度大陆的北缘同时期存在大陆向上挠曲,导致陆源碎屑输入量的快速增加,石英砂岩广泛存在;早白垩世火山岩屑砂岩对应着的印度大陆北缘地层侵蚀加深,使得较深部的深成火山岩暴露并遭受侵蚀;石英砂岩和早白垩世岩屑砂岩所代表的印度大陆剥露时间在空间上的&东早西晚&,说明构造运动首先是从特提斯喜马拉雅的东部开始(大印度与澳大利亚的彻底分离),然后逐渐波及西部的,东西时间差为15~20Ma;由于地壳均衡作用,大陆分离后原先地壳挠曲转变为地壳下沉,发生强烈的构造沉降,故Albian之后沉积一套深水环境下的海绿石、磷酸盐和黑色页岩沉积。

Based on the settings and geological and geochemical characteristics of granitoids of different orogenic belts (exemplified by orogenic granitoids in Altay, East Kunlun, Yanshan in North China, Northeast China and Nanling in South China), the relationships between granitoids and continental crustal growth are discussed, and five modes of continental crustal growth in the continent of China are proposed;they are as follows:(1)the Altay mode of continental growth is that the material and heat of the Paleozoic convertive mantle formed on the background of the Paleo-Asian Ocean were input into the Paleozoic continent and mixed with the materials of the upper crust;(2) the East Kunlun mode is that the basement of the Proterozoic orogenic belt was reworked by the heat input and materials of the Paleozoic-early Mesozoic convective mantle formed on the background of TTG continental crust of the Proterozoic orogenic belt;(3) the Northeast China style is that the Phanerozoic continental crust was reworked by the heat input and materials from the convective mantle formed on the background of the Yanshanian Central Asian orogenic belt;(4) the Yanshan mode is that the Archean basement was reworked by the heat input and materials from the Yanshanian convective mantle;and (5) the Nanling mode is that in South China what was input by the Yanshanian convective mantle into the continent was mainly heat and subordinately materials and the crustal material recycle was the dominant mode for the continental growth (showing zero continental growth).
根据不同造山带花岗岩的形成背景,地质地球化学特征差异,以阿尔泰,东昆仑,华北燕山,东北和南岭造山带花岗岩为例讨论花岗岩与大陆地壳生长的关系,区分出中国大陆的5种大陆地壳生长方式:阿尔泰式是古亚洲洋背景上形成的古生代对流地幔物质,热输入和上地壳混合为主的方式;东昆仑式是元古代造山带TTG陆壳背景基础上古生代—早中生代对流地幔物质和热输入,改造元古宙造山带基底的方式;东北式是燕山期中亚造山带背景上对流地幔物质和热输入改造显生宙陆壳的生长方式;燕山式是燕山期对流地幔物质和热输入改造太古宙基底的方式;南岭式燕山期对流地幔输入大陆的是以热为主,物质为辅,大陆地壳生长是以陆壳物质再循环为主的生长方式。

The main results are listed as following: 1. Phylogeographic study on Croomia The relationships and distribution of cpDNA haplotypes suggested that Croomia had been widely distributed in ancient eastern Asian and northern American; the origin and distribution center of Croomia were concentrated on the mountains comprised Mt.
Croomia亲缘地理学根据叶绿体DNA(trnL-F、atpB-rbcL)单倍型的关系和分布推测,Croomia在古欧亚大陆和古北美大陆有着较广泛的分布;我国的黄山和天目山一带是Croomia的分布、起源中心,其散布路线是从中国大陆到日本,再到美洲古大陆;北美种群与东亚种群分离较早;东亚种的分化时间比较晚。

The main tectonic features of the four stages mentioned above can be summarized as follows, gneissic basement and greenstone belt in the Archean, formation and rifting of ancient continental crust in the Transition, creation and disposal of the first supercontinent Columbia in the Paleoproterozoic-Mesoproterozoic, and the assembly and disassembly of the supercontinent Rodinea under plate tectonic framework in Neoproterozoic.
这四大阶段的主要构造面貌分别是:片麻岩基底和绿岩带盆地,古陆壳的形成与裂解,第一个超级大陆即哥伦比亚超大陆的形成与离散,板块构造体制下罗迪尼亚超大陆的汇聚与离散,反映了大陆岩石圈的形成和由低级向高级的演化,因而每一阶段都有不同于前一阶段的沉积建造、火成岩类型及组合、变质作用、构造样式、构造线方向、变形方式和成矿作用。

The general feature of deformation caused by the collision between two continents also reveals that, during the collision process, apart from a foreland basin and high mountains being formed, there is another compressive depression with an asymmetric structure developed on the side of the obducted plate, which is much easier to be formed when the dip angle of the collisional fracture zone is between 15° and 30° and is the deepest with a dip angle of 30°. This implies that the compressive depression is controlled by both subduction and obduction between two continents.
从大陆与大陆碰挂变形构造特征看,除发育前陆盆地-山脉系统外,在仰冲陆块一侧靠近造山带后缘还发育呈不对称结构的挤压性凹陷,当两个大陆板块碰撞断裂带倾角在15~30°时,该类型凹陷更容易形成,其中以30°倾角对应的凹陷最深,反映其形成可能是大陆碰撞过程中陆块之间相对俯冲和仰冲运动的综合结果。

But the imperfects mentioned abovecouldn't be reasons to deny jury system applied in our country:first,at present time,jurysystem didn't tend to decline which mentioned by some scholars both in civil lawcountries and Anglo-American law countries,but has different development roadrespectively.The overall development tendency of jury system in other modern countriesis good which is valuable for us to use for reference;second,civil law countries havesimilar cultural soil with us,the overall development tendency of jury system in civil lawcountries is good which is valuable for us to use for reference;third,jury system in civillaw countries doesn't influence procedural efficiency,but lift procedural efficiency lot.
但上述不尽人意之处并不能成为否认我国采行陪审制的理由:首先,目前,陪审制度无论是在大陆法系国家还是在英美法系国家,并不是如有些学者所言呈现衰退的趋势,而是各有不同的发展道路;其次,大陆法系国家与我们有相似的文化土壤,陪审制在大陆法系国家中整体发展趋势是良好的,这一点值得我们借鉴;再次,大陆法系国家的参审制不但不会影响诉讼效率,相反倒是可以大幅度提高诉讼效率。
